-
-- If I mark some text and then press ^, then the marked text is deleted.
-  The correct behavior is to put the marked text in the superscript.
-
-- Pressing <down> when cursor is in subscript will move the cursor up
-  (to the base of the subscript) instead of exiting the inset.
-  The same problem happen in fractions
-
-!! If you type something there you will see that the corsor has left the
-!! inset. That's mor or less a "feature". If you don't like it, propose a
-!! method how a subscript inset can figure out what is "optically" lower

-
-?? - After insertion of \sum, the cursor is in invalid location

-- When exiting the formula during selection, the anchor moves to the
-  left of the formula and there's no way to go back.

-// - Scripts are too large. $\log_2$ exceeds inset frame (non-displayed).
-
-- You need two <right> to get past \vec{v}, and all sort of other
-  insetish behavior.
-
-- \vec{several-characters} doesn't work. \overrightarrow does.
-
-- When the cursor is in a subscript (and either isn't at the end of 
-  the subscript or there's no subsubscript), pressing <down> should
-  try to *really* go down (to the next line, or denumerator, or 
-  whatever). Currently it goes *up*. Ditto for superscripts.

- - Formula inside tabular cell: red frame of cell inset and purple 
-   frame of formula can overlap, causing leftovers when leaving

-- the most annoying bug by far: bold is "inherited" to super and subscripts.
- 
-- when you get into equation array mode, the previous equation(s) remain(s) 
- unaligned. I would be soo much faster to have LyX pick the last equal sign 
- from the previous line as a reference for the alignment (and a good heuristic 
- for the 80% of cases, with the advantage that we don't lose anything 
- enforcing it). This is another case that slows down a lot when typing 
- because, as the previous one, requires going back and correcting.
- 
-- the movement is sometimes clumsy inside this arrayed equations: ie. C-a (or 
- "home" are understood as "beginning of the formula" instead of "beginning of 
- the equation". Again, a lot of movement has to be made. I suggest mapping 
- "beginning of doc" with "beginning of formula" and so on (very intuitive), in 
- case you don't deem appropriate the "namespace idea" below.
- 
-//- movement between macro boxes is also weird, but in this one it's perhaps 
-// just me.  
- 

 - I suggest creating a different "kewybinding namespace" for the formulas, 
  since you could put to good use all those keybindings from the menu (M-?, 
  C-?) thath currently do their job PLUS getting you out of the formula.
